RUBBER GLOVE.

Application led September 15, 1923. Serial No. 662,938.

. at Akron, in the county of Summit and State of Ohio` have invented acertain new and useful Improvement in a Rubber Glove. ofl

which the following is a full` clear. andlex act description, referencebeing had to the accompanying drawings.

The general object of the present invention is the' provision of amitten or glove adaptable for use in cleansing garments of line texture.More specifically my invention is concerned with the provision of arubber glove having a palm side and back side zones or clusters ofirregularly grou )ed spurs or projections which, when the glove is wornupon the hand of the user may lie adjacent the palm side of the handwhen the hand grasps a garment. A further object is the provision of anovel method for economicallyT manufacturing such a rubber' glove. Otherobjects of my invention will hereinafter be set forth in the followingdescription which refers to the accompanying drawings illustratingyapreferred embodiment thereof. rlhe essential characteristics aresununarized in the claim.

ln the drawings, Fig. l is a plan view of a glove made in accordancewith my invention and showing the palm side of the glove; Fig. 2 is asimilar View showing thc back side of the glove; Fig. 3 is a viewillustrating the manner of wearing and using the glove when washinggarments of fine texture; Fig. 4 is a large cross-sectional View takensub stantially along the lines 4 4 of Fig. l; Fig. 5 shows the use of apair of gloves.

In cleansing garments of finey texture it is usually the domestic customto rub the garment between the knuckles and palms of the hands, using ofcourse, water and soap as a cleansing medium. When the soap contactswith the skin of the hands, however, it acts as a lubricant and itbecomes necessary to iirmly grasp portions of the arment and thus cleanthe arment by ru bing it between the knuck es.

Attempts have been iliade to manufacture a mitten or glove for-thispurpose wherein waterproof leather or fabric was used. there beingroughened surfaces provided on the love or pleces of rope or similarmaterial, formed to give a crude representation of a washboard.

My invention contemplates the provision of rubber gloves having cleaningor rubbing surfaces irregularly formed thereon, which are formed on thegloves in such positions that when the glove is being worn for thepurpose of cleaning garneients, these roughened surfaces will lieadjacent to each other, particularly when the hands are doubled intofist. form when gripping a garment. In the present instance. I form aglove of rubber b v modern approved methods whereby the palm side of thefingers of the glove are of the usual form as well as the major portionof the palm, whereby the glove walls may. be suliciently thin to permitthe use thereof for other purposes than herein specilied.

Figs. 1 and 2 show a rubber glove A, which may be formed in varioussizes wherebv the thumb portions B, and finger portions C may alwayssnugly fit the wearers hand.

Upon the palm of the glove adjacent the thumb portion B, I form acluster of irregularly arranged projections of varying height as isshown at D and a similar cluster E adjacent the little finger portion C,these clus- Iters being formed closer to the wrist portion F of theglove than to the thumb and finger portions. As shown ain this figure,the thumb portion B and the palm side and ends of the finger portions C,are not encumbered in any manner whereby the sensibility of the hand isnot lost to the wearer when handling objects.

Upon the backs of the finger portion C, I

. form similar clusters or projections E which will lie immediately overthe rst knuckle of each finger when the glove is worn by the user,whereby when the fingers are folded to represent a fist, as shown inFigs. 3 and 5 the clusters G are brought into juxtaposition with thepalm clusters D and E. The palm side ofthe thumb portion B may have asimilar zone of clusters K formed thereon.

Each set group of clusters may comprise outer rows of slight projectionsH and inner rows of projections J, each row of rojections being slightlygreater in height than its adjacent outer row, thus facilitating thecontacting or rubbing of the various projections with the surfaces ofthe fabric being cleansed.

An article such as I describe may be very economically manufactured byusing formsv corresponding to the size of glove to be canized to theOlove Wall.

made, which forms may be dipped in a liquid rubber compound; the numberof dippings depending upon the thickness of Wall desired in the glove.The clusters G, E, etc., are preferably made in molds in the form ofpatches of semi-cured or uncured rubber. These patches may then beapplied to the form carrying the uncured dipped rubber before the formis submitted to the curing operation. The forms may then be subjected toeither a gas cure or an acid dip cure, whereupon the patches become Vul-The glove may then be stripped from the form. Y

If desired, the gloves may be formed in molds in which case the clusterswould then be directly molded on the rubber Wall, thus eliminating thenecessity of separately forming the patches. I find, however, that theform dipping process is more economical and that the patches becomethoroughly vulcanized to the finger and palm Walls of the glove andremain so throughout the life of the use thereof.

From the foregoing description of my in-y vention it will be readilyseen that I provide foregoing description of my invention that a verypractical glove construction is afforded which is very durable and whichmay be very economically manufactured, and furthermore that the rubbingsurfaces are formed on the glove in such a manner as to be extremelyeffective in vquickly cleaning line texture'garments Without anyresulting damage thereto.

It should be particularly noted that by' forming the glove on a dippingform, and then applying molded portions having irregular roughenedsurfaces affords a very economical method of producing thin Walledrubber articles having thickened wall zones at the places Where thearticle is subjected to the greatest Wear.

I claim:

A glove comprising an all rubber body having finger and thumb portions,such portions having thickened walls in zones, said thickened zoneportionshaving projections extending from the surface thereof and thethickened portions being integral elastic portions of the glove body.

Intestimony whereof, I hereunto aiix my signature.
